This comparison is lame. In early 2018, many major incidents happened, the biggest being the conflict surrounding Chinese and Indian sanctions on bitcoin and cryptocurrencies.

The vast majority of institutional investors have created a huge incentive for bitcoin's value. ICOs do not have many ways to profit, but mainly decentralized finance (Defi) has supported the development of altcoins in a more macro direction. Though, I think the bear market is still there. but the resistance is now higher.
